Built for Speed
More aerodynamics than ever: developed and designed with Team Astana, the Air Speed has been tested with other helmets to check the aerodynamic resistance inside the Wind Tunnel in Magny-Cours, in France, turning out to be the best at an average speed of 40 km/h.
Beyond the wind tunnel
Studies have proved that about 20% of the aerodynamic drag depends on the bicycle used during competitions, while the remaining 80% is due to the athlete’s position on the saddle. The helmet is therefore the fundamental element to minimize the frontal area and to determine a better aerodynamic penetration.
And then the wind tunnel tests…
Not only with three-dimensional simulation supports, using CFD software, but also taking into account the numerous variables, especially in competitions, when the rider hardly remains on the saddle in the same position, moving the head countless times. And here comes our Limar Airspeed: designers found the perfect combination between aerodynamic advantage (wind tunnel test) and better dynamics both on open roads and in velodromes (tests in real-life environmental conditions).
It was during one of the recent road training sessions in Calp and indoor at the Valencia velodrome, that the Astana Team riders were able to really test the helmet. They got incredibly excited of the characteristics that make AIR SPEED the ideal helmet.
Mips Technology Integrated
Mips Air is a rotational management system developed and designed to be the lightest system possible to help reduce rotational energies otherwise transferred to the head during an impact or crash. The Mips Air technology is integrated into the padding of the helmet and enables and 10-15mm of relative movement between the energy absorbing layer and the padding. The relative movement of the Mips Air is enabled by having a backing of polycarbonate PC with a special low friction treatment and being held by specifically designed fixations enabling movement in all directions. By being integrated into the padding, the system is as light as it gets and designed to fit each specific helmet and size, barely being visible to the user and adding only limiated weight to the helmet.
